Netgames do weird, weird stuff

Non-green resolutions are not supported

Changing tilesets does not change decoration, but that'll be your fault

Weird tile collision. For walls, disable top and bottom collision.

Only the Homing Thok and Fly abilities are implemented.

Splitscreen isn't "split screen".

No bot AI code, can only be controlled by Player 2 controls.
* Essentially, Singleplayer with bots is the same as Splitscreen.
